It will be observed that the washer dhas its outer surface, which is in contact with the lead, inclined or beveled. The object of this is to give support to the lead at the upper end of the neck by spreading it slightly at that point, as clearly shown in the drawings. It also slightly increases the exposed surface of the lead upon which the brass cover 13 rests when placed in position. Another important function of this construction is, that the washer d prevents the lead at the inner edge of the mouth of the trap from being worn away or compressed out of shape by the repeated removing and replacing of the cover 13. of leakage of sewer-gas through the cover, as the inner surface of the cover inside the flange 6 is compressed tightly when the cover is in place against the top surface of the neck 1),

whose inner edge is prevented from becoming ragged or worn by the washer d, as described.

Upon the outside of the neck I), I employ a thin but sufficiently rigid metallic ring, f, which may be so shaped at its bottom as to readily conform to the upper extremity of the shoulders a a, upon which it rests, as shown in the drawings. This ring f extends almost to the top of the neck I), as shown, the purpose being to leave the outer edge of said neck on protected, so that when the cover Bis screwed into position the flange g of the cover will slightly compress the lead of said edge of the neck onto the ringf. By this means a secure lead-packed joint is produced at the point desi gnated, and the lead at that point is prevented from becoming unduly worn away by the hard metal foundation afforded by the ringf.

The cover B is provided with the usual wrench-pins, to facilitate its attachment to and disconnection from the trap.

By my method of manufacture the trap can be made of considerably less weight than the hand-made trap, and hence its cost of produc tion is greatly lessened.

In this style of trap itis understood, of con rse, that the inlet and outlet pipes may be inserted in a direct line, one above the other, or in any I thus prevent any liabilityother suitable relation, one to the other,according to the position the trap is. to occupy with reference to the structure to which it is connected.

The traps will be made of the several standard sizes.

Having thus described my inventiomwhat I claim as new, and desire to secure by Letters Patent, is-- 1. Asoft-metal plumbers trap the mouth of whose cleauingout opening is provided with a female screw-threaded nut and with a fixed annular metallic washer embedded above said nut, securing it in position, and in conjunction therewith forming a continuous sur-- face of metal harder than the body of the trap, substantially as described.

2. A softmetal plumbers trap the mouth of whose cleaning-out opening is provided.

with a female screw'threaded nut and with a fixed annular metallic washer embedded above said nut, and having its outer surface beveled or inclined for securing the nut in position, said not and washer forming a continuous surface of metal harder than the body of the trap, substantially as and for the purpose set forth.

3. A soft-metal plumbers trap whose cleaning-out opening is provided on its interior with an embedded screw-threaded nut and @eXteriorly with a metallic strengthening-ring, as f, substantially as described.

4. A soft-metal plumbers trap the mouth of whose cleaningout opening is provided with the embedded screw-threaded nut c and metallic retainingwasher 01, forming a con ti nuons surface of metal harder than the body of the trap, and with an exterior strengthening-ring, the upper edge of which is embedded int-he soft metal of the trap, substantially as described.
